The idea of high school students needing to carry ID only came about when schools grew too large for every student to be known, for safety reasons. My old high school is still too small to need them. North Farmington High School in Michigan has over 1200 students, but they are still pretty easygoing about student IDs. It's an annual tradition there for seniors (who the staff know pretty well by then) to dress up and pose as pop culture characters for their ID photos!
They chose characters from TV, movies, video games, cartoons, anime, and even internet memes.
Students have been posting their new IDs on Twitter with the hashtag #NFID20. You can go to the hashtag and see quite a few more.
